DOCREADER — READ PDFS & EPUBS, LISTEN OFFLINE, KEEP YOUR LIBRARY LOCAL DocReader is a full-featured reader for study, work, and leisure: open PDFs and EPUBs from your device, resume where you stopped, and switch to read-aloud with highlighting when your eyes need a rest. Use your system voices or optional offline engines you download once—no account with us required. Navigation keeps essentials one gesture away: open files, Project Gutenberg, quick theme and TTS shortcuts, full Settings, and your recent list. READ-ALOUD & VOICES Start, pause, resume, or stop from the document toolbar; highlighting tracks speech when content supports it. Skip configured headings or lines during read-aloud for manuals and reference EPUBs. Pick your engine: System TTS uses built-in OS voices—no extra download. Kokoro-style offline voices (Sherpa ONNX) prioritize natural speech via an optional pack; synthesis stays on-device after install. Supertonic is a separate optional pack for very fast on-device speech—great for long documents or cooler phones on marathon listens. Adjust rate and speaker where offered; optionally keep the screen awake during playback. READING COMFORT Light, dark, or system theme. PDF dark mode is tuned for legibility without harsh glare. Set default PDF and EPUB view scale (fit page, fit width, or other offered modes) and document scroll speed. Quick toggles and in-document panels expose theme, fonts where available, and key reading settings without deep menu hunting. The full Settings screen groups theme, scroll speed, scale defaults, voice-pack status, TTS engine selection, speakers, and keep-awake options in one place. While viewing a document, open TTS settings from the drawer to change engines, speakers, or start voice-pack downloads. LIBRARY & EVERYDAY WORKFLOW The home screen lists recent documents with timestamps for quick return visits. Open files through the system picker; imports stay under your control, not a proprietary cloud. With Remember reading position enabled, DocReader restores the last page or section next time. On iOS, materials may appear under Files when the system surfaces the app documents folder—handy alongside your other backups. FORMATS FOR REAL FILES Smooth PDF viewing with zoom and default scale modes tuned separately from EPUB. Reflowable EPUBs suit novels and structured nonfiction. Beyond books, open many plain-text and code-adjacent types—Markdown, logs, subtitles, configs, JSON, CSV, common source extensions, and more—plus HTML and popular image formats. Unsupported archives or office packages may hand off to another installed app when the platform allows. SCANNED PDFS / OCR When a PDF has no text layer, on-device OCR (where the platform supports it) recovers text for reading and read-aloud and supports page-space highlights—without sending page images to a DocReader cloud OCR service. PROJECT GUTENBERG From the drawer, browse and download public-domain titles when online; files join your local library for offline reading and listening. Catalog hosts are third parties; availability may vary. DESKTOP & MOBILE Use DocReader on phones, tablets, and supported desktops with layout and window chrome suited to each environment—including draggable title areas on desktop where provided. PRIVACY IN BRIEF Library metadata, preferences, and positions stay on your device. The network is used when you choose features that need it—Gutenberg discovery/downloads or optional voice archives—not to silently upload your private collection. See the linked Privacy Policy for details. SUPPORT Questions or bugs: 2asoftwaredevelopers@gmail.com — include device, OS, and app version (build shown in the drawer when available). Thank you for choosing DocReader—read deeply, listen comfortably, stay in control of your library.

KlickBox is a task manager for people who work alongside an AI agent. You keep the list. Your agent helps clear it, briefs you out loud, and sends you pages and papers to read. ▸ Listen Your agent records spoken briefings and sends them to your phone. Press play and start walking: what is due, what changed status, whatever you asked it to look into. Each one arrives with a transcript for when you cannot listen, filed under categories you name yourself. Hold the microphone to reply out loud, or tap the pencil to write instead, and your agent collects it on its next run. Share a recording or its transcript with a tap. Finished briefings are archived to your own iCloud Drive. You will find them in the Listen tab. ▸ Reads Your agent can also send you something to read: a newsletter it wrote overnight, a paper it found, a report, an itinerary. Each page or PDF lands in the Reads tab, opens offline, and never loads anything from the web, so it renders the same on the subway as it did on Wi-Fi. Tap to make the text larger. Share a Read as a PDF or pass along the original file. Once you have opened one, your agent can see that you read it. Reads are kept in your own iCloud Drive. ▸ Bring your own AI agent Open Bring Your Own Agent in Settings and copy the Agent Document: your API Key, the API address, and the docs, ready to paste into OpenClaw/Hermes, Claude Code/Cowork, Codex, or anything else that can read docs and call an HTTP API. From there, it can capture, prioritize, defer, and complete Tasks, work through your Idea Bank, record briefings, and send Reads. We never see your prompts. The agent runs where you run it, on your own provider account. ▸ The Idea Bank A second home for things that aren't Tasks yet. A thought, a quote, a link, a screenshot, a PDF, a voice memo, filed under a Project such as a book chapter or a keynote. Every Idea is a thread you keep adding to. Your agent reads it, acts on it, and marks it as captured. Add something later and it reopens. ▸ The app • A Tasks list that auto-sorts by what matters now, with Later and the Archive one tap away • Tap to complete, swipe to defer, drag to reorder • Task Families: group big work into parent/child subtasks • Tags, Checklists, Comments, and Attachments • History that groups itself: briefings by category, the Archive by tag, ideas by project • Storage settings for Listen and Reads: keep everything forever, or clear what you have already heard or read after 30, 90, or 365 days • Home screen widgets with one-tap completion, plus lock screen widgets • Works offline, syncs in the background • Sign in with Apple, Liquid Glass design (iOS 26 or later) ▸ Privacy Your tasks live on your device and on a private Supabase project we host on your behalf. We don't sell or share your data. Briefing audio and Read documents pass through a mailbox that deletes them on delivery, and the lasting copies sit in your own iCloud Drive. Opening a Read doesn't contact the server. Replies go to your agent, not to us, and KlickBox never transcribes them. Delete your account, and everything in it, from Settings.
